Introduction

1. Introduction

The PRIMUS

R

660 Digital Weather Radar System is a lightweight,

X–band digital radar with alphanumerics designed for weather detection

(WX) and ground mapping (GMAP).

The primary purpose of the system is to detect storms along the

flightpath and give the pilot a visual indication in color of their rainfall

intensity. After proper evaluation, the pilot can chart a course to avoid

these storm areas.

WARNING

THE SYSTEM PERFORMS THE FUNCTIONS OF

WEATHER DETECTION OR GROUND MAPPING. IT SHOULD

NOT BE USED NOR RELIED UPON FOR PROXIMITY

WARNING OR ANTICOLLISION PROTECTION.

In weather detection mode, storm intensity levels are displayed in

four bright colors contrasted against a deep black background.

Areas of very heavy rainfall appear in magenta, heavy rainfall in red,

less severe rainfall in yellow, moderate rainfall in green, and little or no

rainfall in black (background). If selected at installation, the antenna

sweep position indicator is a yellow band at the top of the display.

Range marks and identifying numerics, displayed in contrasting colors,

are provided to facilitate evaluation of storm cells.

Selection of the GMAP function causes the system parameters to be

optimized to improve resolution and enhance identification of

small targets at short ranges. The reflected signal from ground

surfaces is displayed as magenta, yellow, or cyan (most to least

reflective).

NOTE: Section 5, Radar Facts, describes a variety of radar operating

topics. It is recommended that you read Section 5, Radar

Facts, before learning the specific operational details of the

PRIMUS

R

660 Digital Weather Radar System.

Introduction

The radar indicator is equipped with the universal digital interface (UDI).

This feature expands the use of the radar indicator to display

information such as checklists, short and long range navigation

displays (when used with a Honeywell DATA NAVt system) and

electrical discharge data from Honeywell’s LSZ–850 Lightning Sensor

System (LSS).

NOTE: Refer to Honeywell Pub. 28–1146–54, LSZ–850 Lightning

Sensor System Pilot’s Handbook, for more information.

System Configurations

2. System Configurations

The PRIMUS

R

660 Digital Weather Radar System can be operated in

many configurations to display weather or ground mapping information

on a radar indicator, electronic flight instrument system (EFIS) display,

multifunction display (MFD), or on a combination of these displays. The

various system configurations are summarized in the following

paragraphs and shown in figure 2–1.

NOTE: Other configurations are possible but not illustrated.

The stand–alone configuration consists of two units: receiver

transmitter antenna (RTA), and a dedicated radar indicator. In this

configuration, the radar indicator contains all the controls to operate the

PRIMUS

R

660 Digital Weather Radar System. A single or dual

Honeywell EFIS can be added to the stand–alone configuration. In such

a case the electronic horizontal situation indicator (EHSI) repeats the

data displayed on the radar indicator. System control remains with

the radar indicator.

The second system configuration uses an RTA, and single or dual

controllers. The single or dual EFIS is the radar display. Since there is

no radar indicator in this configuration, the radar system operating

controls are located on the controller. With a single controller, all cockpit

radar displays are identical.

The dual configuration gives the appearance of having two radar

systems on the aircraft. In the dual configuration, the pilot and copilot

each select independent radar mode, range, tilt, and gain settings for

display on their respective display. The dual configuration time shares

the RTA. On the right–to–left antenna scan, the system switches to the

mode, range, tilt, and gain selected by the left controller and updates

the left display. On the reverse antenna scan, the system switches to

the mode, range, tilt, and gain setting selected by the right controller

and updates the right display. Either controller can be slaved to the

other controller to show identical images on both sides of the cockpit.

NOTES: 1. When WAIT, SECTOR SCAN, or FORCED STANDBY

are activated, the radar operates as if in single

controller configuration. This is an exception to the

ability of each pilot to independently select modes.

2. In the dual configuration, the pilots can use the slave

feature to optimize the update rate of each side’s

weather radar display to meet the needs of the

situation. With one controller turned off, both cockpit

displays are updated on every sweep of the radar, but

control of the radar is only on one side. With each

controller operating, each side has control but each

side is updated with new radar information on every

other sweep of the antenna.
